Abstract: A detonation coating apparatus that coats a substrate with a coating powder which is propelled by the products of a detonation. The present invention increases the rate at which the coating is applied by increasing the detonation rate of the combustible gas mixture.

Title: Non-invasive cuffless determination of blood pressure
Inventor: GOLUB HOWARD L
IPC: A61B5/352
Filed: 1997-10-14
Granted: 2005-08-23
Abstract: Arterial blood pressure of a subject (10) is determined by detecting the EKG (12) and selecting a fiducial point thereof, preferably the R-wave. Apparatus, preferably a photoplethysmograph (14) is provided for monitoring blood volume versus time at a selected location on the subject's body such as a fingertip (16). A time difference between th e occurrence of the selected fiducial point on the EKG and a selected change in blood in volume at the selected body location is determined. This time difference depends on the arrival time of the pulse at the distal location in addition to the shape of the blood volume versus time curve. Heart rate is determined from the EKG. The arterial pressure is computed from pulse arrival time, volumetric wave shape and instantaneous heart rate for each pulse. Methods are disclosed for determining diastolic pressure, systolic and mean arterial pressure. In another aspect, artifact detection and rejection are enabled. The invention provides for a continuous measure of blood pressure in a non- invasive, cuffless manner.

Title: Caged slip system and release methods
Inventor: DOANE JAMES C
IPC: E21B23/01
Filed: 1999-10-18
Granted: 2005-01-04
Abstract: An improved cage slip system is disclosed. The cage is constructed so that the cones which actuate the slips extend into the cage openings. The radial extension of the slips is limited so as to retain them if they are extended in an unsupported situation. The cones have a maximum outside dimension equal to the outside dimension of the cage so as to increase the rating of the slips by increasing the bearing area of the cones on the slips. The beneficial features of the cage design are retained while a greater degree of radial expansion of the slips is possible allowing minimization of tool inventory for situations where a lighter wall casing requires further slip extension. The release system allows the lower cones to be driven out from under the lower slips, thus facilitating release of the grip of the lower slips from the casing for extraction of the packer. The mechanical release is functional through the mandrel, whether tension or compression is placed on the mandrel.     Alternative designs are presented for the capture of the lower cone by the cage.
